Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China
Martin72:
By the way, something that may be interesting:
Note the pic with the FFT 16bit - You get the same result in normal mode when decreasing vertical resolution under 500µV(200µV, 100µV) and bandwith will be automatically limited to 20Mhz then.

Just noted the frequency is indicated as ~119MHz, shouldn't that be 120MHz?
Best,

Last pic a 120Mhz sinewave with 1Vpp amplitude, Hi-res 16 bit active, amplitude decreased to under 700mVpp.

Hallo,
interestingly, after HIRES, the sample rate is still 4 GSa/s. So no points are decimated.
Best regards

Hm, you're right..
Will check it after work.

It will be 4GS/s.. ERES and HIRES are running average filters.. they don't change number of sample points...Just lowpass filter it..
Also with Averaging, no resample happens, just average point by point between different triggers.
